secuTrialR vs segregatr: at a glance
What is secuTrialR?
A Swiss clinical-trial data reader that surfaces once every couple of years to clear check notes.
secuTrialR reads and prepares data exports from the secuTrial clinical data management system for analysis in R. Development is sporadic and maintenance-shaped: the 2025 release bundles six pull requests covering dependency breakage, quote handling in free text fields, a generalised URL builder and CRAN check notes. Its release notes are largely merge messages and submission records rather than descriptions of what changed.
What is segregatr?
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.

secuTrialR

◆ Current state
secuTrialR reads and prepares data exports from the secuTrial clinical data management system for analysis in R. Development is sporadic and maintenance-shaped: the 2025 release bundles six pull requests covering dependency breakage, quote handling in free text fields, a generalised URL builder and CRAN check notes. Its release notes are largely merge messages and submission records rather than descriptions of what changed.
◆ Where it's heading
The visible history has two distinct phases. The 2020 releases are a CRAN review loop — four submissions in two weeks, each note recording only the submission itself. After that the package goes quiet for years at a time, resurfacing when R or its dependencies break something. The one substantive thread is robustness against real-world export data, with the free-text quote fix as the clearest example. The 2025 release's own changelog spans 1.1.1 to 1.3.3, so several intermediate versions exist that this feed never showed.
◆ Prediction
Expect the next release when a dependency or CRAN check forces one, since that has triggered every release since 2020; the notes give no indication of planned feature work.
segregatr
0.0ANALYTICS
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
◆ Current state
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.
◆ Where it's heading
The through-line is coverage of awkward real-world pedigrees rather than new statistics. Loops were handled for the core score in 0.3.0 and then extended to liability classes in 0.4.0, so the same structural capability is being pushed through the codebase feature by feature. The 2025 release moves in a different direction, relaxing the requirement for a designated proband. Development is slow and steady, roughly annual, and tracks its pedtools dependency closely.
◆ Prediction
Expect the next release to continue relaxing modelling constraints — the pattern of retrofitting each new capability across loops, liability classes and inheritance models is unfinished — rather than expanding beyond segregation scoring.

Frequently asked questions
What is the difference between secuTrialR and segregatr?
Both compete on the same themes — r-package — within Analytics. secuTrialR and segregatr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is secuTrialR better than segregatr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. secuTrialR and segregatr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
